Document Type and Number:
Japanese Patent JP4485726
Kind Code:
B2
Abstract:
The invention relates to a surface-cleaning device (61, 63) which has a base part (69) and a cleaning part (67) having a substantially flat contact surface (71) for contact with a surface (41) to be cleaned and which is rotatable relative to the base part about an axis of rotation (77) extending substantially perpendicularly to the contact surface. According to the invention, the cleaning part is pivotable relative to the base part about a pivot axis (105) which extends transversely to the axis of rotation, and the base part is so constructed that a component (93) is present and exerts a pre-tension force, preferably a pre-tension torque (Mp) on the cleaning part about said pivot axis. As a result, the contact surface is substantially completely in contact with the surface to be cleaned, and, when the surface-cleaning device is moved over the surface to be cleaned, the cleaning part automatically rotates about the axis of rotation under the influence of a friction force (W) present between the surface to be cleaned and the contact surface.In a preferred embodiment, the component (93) for exerting the pre-tension torque has a roller member (95) which bears upon a roller track (99) of the cleaning part (67) under the influence of a pre-tension force (F).The surface-cleaning device according to the invention is used in a vacuum cleaner according to the invention, wherein the surface-cleaning device is accommodated in a suction attachment to increase the cleaning performance of the vacuum cleaner.
